The Facts: Mike Williams did not practice on Monday while dealing with a back injury.

Diehards Line:Williams left the Chargers' Week 14 game with the back injury but Keenan Allen is also listed on the injury report so it's hard to say how much this actually means for Williams. His practices later in the week will tell us more about his status. If he does miss time, Jaylen Guyton would take over as the primary field-stretcher and would have some deep flex appeal.
